Re: To Turbulize or not

I like this idea so much that I went searching the net for a source of suitable material. I found a 21-foot roll of 0.5" wide 304 stainless (no thickness given) on Grainger for under $9. (Item 3A550) Apparently this is the feedstock for a (presumably very heavy-duty) Dymo label maker. Does this soun...

Re: Around the country

For your eastbound leg, let me suggest that you avoid I-90 or I-80 but head south from Montana to Colorado. There are a few clubs in the Front Range area and the Colorado Live Steamers are out on the plains near I-70. There appear to be a few clubs in northeast Kansas and more in Missouri. From ther...

Re: Radius of an arc or segment

On this topic, let me ask: Is there a recommended technique for hand-bending rail? I suspect that clamping in a vise and forcing will likely result in a tight bend at the edge of the vise and an otherwise straight section. I purchased a disassembled layout a few years ago, and have been able to sele...

Re: weird RR machine

Mechanisms like this were also important in high technologies in the small-power-transfer, high-precision regime as "mechanical integrators" (as in machines that performed the basic operation of integral calculus). Such technologies reached their peak of development at the same time as steam locomot...

Re: FRUSTRATED with threading tubing

One thing that I find helps a great deal is to use the Sherline to pre-cut a taper on the end to be threaded and then (with the headstock still offset) use the threading kit to cut threads to maybe half the final depth. Then I hold the tubing in a flaring-tool jig. Now the NTP/MTP die aligns easily ...

Re: Power Reverser questions

Just a thought: If you are trying to pack a servomechanism into the small space of scale power-reverser it might be better to make it electrically operated. The direct electrical analog would be opposing solenoids run by an analog proportional control, but that would drain a lot of current. Somethin...

Re: Steam Dome Throttle

Thanks for the tips about the problems with lightweight teflon. After considering the potential problems of working with very small parts like springs inside the steam dome (and losing said parts into the boiler) I decided to just try putting a weight onto the stud, above the L-bar. I cut off a 1/2"...

Re: Steam Dome Throttle

I'm sorry to be so late to this thread, but my locomotive is located at a secondary residence. I want to show Tom Artzberger's design for the steam dome throttle in the RGS 20, The view is looking down into the steam dome, and the throttle is about halfway open. The white throttle disc is PTFE, mach...

Re: Water treatment for iron boiler?

If it really is iron, wouldn't be too worried about it. But as Pat said, these days the chances are it is actually steel. As for water treatment, I wrote about water treatment in the Sept./Oct. Live Steam magazine. Marshall Black's article on water treatment was reprinted in the same issue. Marty, ...

Hi Folks;
With a lot of help from some awesome friends, the a majority of the parts of the Superscale business have been transferred to BLW LLC in Pennsylvania.
Could you perhaps post a web address for your business?

Re: Blower

Is "dissolved oxygen" different from the oxygen that the boiler water is actually made of? Yes, it is. The oxygen in the water is one oxygen atom bonded to two hydrogen atoms. The oxygen in the atmosphere that dissolves in water is molecular oxygen: two atoms of oxygen bonded together. A water mole...

Re: Wood Firing a Chloe

Since optigman mentioned mountain cedar, let me offer a warning, based upon many Boy Scout campouts in Texas: The smoke from mountain cedar is a very powerful allergen, and quite a number of people will develop skin rashes from exposure and an asthma-like response from inhaling it. Be careful.
